In 1920 the survivors of a luxury liner are stranded on a strange island in the North Atlantic inhabited by small red demon-like creatures very similar to that Zuni fetish doll in Dan Curtis' TRILOGY OF TERROR. While trying to avoid being consumed by the diminutive monsters the survivors also have to avoid the pools of acid that inexplicably dot the landscape. As for what the creatures ARE very little is explained. The survivors are so busy trying to run away or getting killed by them that there isn't any time. Plus, I think the lack of explaination adds to the unique strangeness of the movie.
